Two quality stars have already departed from Liverpool, which can lead to a slightly poorer performance on the field. The two players who left the club too soon should be replaced by new players. Liverpool must think they can sign better players than left.
Klopp is really taking a risky move by selling their two veteran midfielders, it's similar like Chelsea. Although the performance of both Chelsea and Liverpool in club friendlies are good enough, but we don't know what will happen in the real match.
Chelsea and Liverpool lack of midfielders.
Manchester United lack of strikers.
I would say Manchester City, Arsenal and Newcastle United are shining in this season.
